This project aims to identify the gaps between BC Energy Step Code airtightness requirements and the construction industry's understanding of building airtight envelopes to support meeting those requirements more predictably and avoiding final blower door test failures. The report examines the results of an industry-wide online survey identifying trades that can most benefit from support and at what stage(s) of construction practices can be improved to construct an airtight building.
